Science Fair Project Idea
thumbnail Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

thumbnail Is that right side of your brain yearning to express its artistic side? This is a project that beautifully blends art with science. Learn about light and colorful shadows in these experiments where you mix and match various colors of light to create a mini light show and shadow wall. You might be surprised at the colorful hues you'll find lurking in the shadows. Read more

Science Fair Project Idea
thumbnail Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… Read more

Science Fair Project Idea
thumbnail You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

thumbnail Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Science Fair Project Idea
thumbnail Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more

thumbnail Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items that are blue in color have the same dye, called FD&C blue 1. In this chemistry science fair project, you will build a simple colorimeter, a device that measures the concentration of colored chemicals in solutions. You will use the colorimeter to measure the concentration of blue dye #1 in sports drinks, and to track the rate at which the… Read more

Science Fair Project Idea
thumbnail Have you ever seen a tortoiseshell cat? "What kind of cat is that?" you might ask. A tortoiseshell cat has two different fur colors, black or brown and red or orange. The gene that gives rise to the red or orange fur color is on the X chromosome. And did you know that most tortoiseshell cats are female? That's because female cats have two X chromosomes, while males only have one, which allows the females to express two different color combinations! Try this science fair project to figure out… Read more

Science Fair Project Idea
thumbnail We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more
